RAIL-FASTENING.

Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed July 19, 1912. Serial No. 710,501.

To all whom it may conccrm= Be it known that I, SHERMAN EIsNAnoLn, a citizen of the United States, residing at Columbus, inv the county of Franklin and State of Ohio, have invented certain new and useful Improvements in RaiLFastenings, of which the following is a specification.

The present invention relates to improvements in rail tastenings for railway rails, and is designed to provide rail fastening device for iisc in connection with metallic *ailwav ties which will be comparatively inexpensive of production, durable,'and simple in construction and operation.

The invention consists essentially in the novel combinations and arrangements of the clamp plates adapted to overlie the base flange of a rail and the devices by which these clamp plates are secured to the tie.

In the accompanying drawings I have illustrated one example and a modified form of clamp plate, and the means for securing the plates to the ties, constructed according to the best modes I have so far devised for the practical application of the principles of the invention.

in the drawiugs:Figure 1 illustrates a side elevation of a tie with the railshown in dotted lines, and at the left it shows the form of clamp plate used. at a rail joint, the right end showing the usual form of fastening the plate to the tie and clannning the rail to the tie. Fig. 2 is a top plan view of Fig. 1. Fig.3 is a view of oneend oi the. tie, Fig. 4 is atop plan view of Fig. 3. F 5 is an enlarged detail sectional view of the tie showing the plate securing means, and Fig. 6 is a. detail sectional view at right angles to Fig. 5.

in the preferred embodiment of my invention as illustrated in the drawings, the rail fastening device is shown in connection with a metallic tie, as 1, which is prefen ably of an I-beam, formed with the upper flanges 2, 2, and base flanges 3, 3, and the curved under surface 4 of the beam 1 is designed to resist side thrust, it being understood of course that the base flanges and web (if the tie are embedded in track ballast m": the railroad. The rails 5 (dotted lines Fig.1) are secured on the upper surface of r the upper flanges 2 by means of pairs of clamp plates 6 and 7, and the clamp plates are in turn attachable to the web and upper flange of the tie. The clamp plate 6 is pro- 1 vided at its underside with aloop 6 adapt- I ed to pass through the slot or opening 6* I in the upper'fiange 2 of the tie. By means of the wedge bar 6 and its pin 6 which holds the wedge against displacement after passing through the slot 6 in the web 1 of the tie and the two loops 6, the clamp plate is securely held to the tie andthe rail in turn t is held to the tie by the extension of the clamp plate. The clamping plate 7 which is located directly opposite the plate 6 is arranged and constructed to be adjustable, I purpose is provided with an I arranged in pairs at the un- The lug 7 is provided with a toe 7 and a heel 7 which it will be noted in Fig. 5 provide a foot of greater length than the length of the slots 7 in the tie flange 2, and through which the foot is passed. By means of the wedge bar 7 which is passed through the slot 6 in the web of the tie and rests on the toe 7 of the and for this integral lug 7 derside of the plate.

lugs 7 this clamp plate may be adjusted and held in position, the bolt- 7 drawal of the wedge bar.

in Fig. 1 at the left where illustrated, the plates 6 and 7' are formed with long bars 16 and 17 to. serve the purpose of the customary fish plates.

In use, the clamp plates 6 are always used preventing witha rail, joint is on the right side of the rail, in order to pre-.

vent unintentional or accidental change of gage betweent-he rails. While the adjustable or sliding clamp plate-7 is used at a point on the rail opposite the plate 6.

In using the invention in connection with switches .sidings, cross-overs, etc., it will be understood that the holes as 6 6 and 7 are to be located at the required points in the ties.

Having thus fully described my invention, what I claim cure by Letters Patent is: l The combination in a rail fastening with as new and desire to sea tie having a fiat head and vertical web In testimcny-whereof 1 aifix my signature of a clamp plate formed with lugs passed in presence of two witnesses.
